i" aZZ whom it may concern/.-

Be it known that we, GEORGE H. MILLEN and EDWARD MoUssEAU, citizens ofCanada, residing at Hull, in the county of Ottawa and Province ofQuebec, Canada, have invented certain new and useful Improvements inPlug Box Machines; and we do hereby declare the following to be a full,clear, and exact description of the same.

Our invention relates to the manufacture of paper tubular boxes, such asare commonly known by the name of plug-boxes, and which are made in twoparts, one end of each part being closed, the deeper part, which we willfor convenience herein call the box,

being made smaller in transverse sectional area than the other part,which we will call the cover, so as to slide into it.

Among the objects sought to be obtained by 2 our invention are, themanufacture of plugboxes by means of continuous onward rotary motion ina box-making machine and the speedy production of complete boxes at theexpense of little labor.

The paper of which the boxes are to be made is prepared for the machinehereinafter described, and which embodies our invention, by cutting itinto strips of any convenient length and of a width equal "to the depthof 0 the box and its width. The paper thus prepared is madeintoa rolland placed on a reel, from which it is taken by the machine in an evenand uninterrupted motion. After leaving the reel the paper ribbon firstpasses down 5 to a type-roll, which stamps upon it at regular intervalsthe inscription or device which the boxes are to bear. From this itpasses to a gluing-roli, by which the glue is deposited on the paper inthe shape and quantity de- 0 sired. It is next seized by a foldingmechanism, cut off by shears, and the sides and end of the box-piecefolded up and held until the glue has set, after which it is shoved fromthe machine finished.

In the following description of our invention reference will be had tothe accompany-- ing drawings, in which-- Figure 1 is a plan view; Fig.2, an elevation of one side of the machine; Fig. 3, an eleva- 50 tion ofthe other side of the machine. Figs. 4

and 5 are respectively a rear elevation and section of the standardwhich supports the camplate, drawn to double the scale of the previousfigures. Fig. 6 is a face view of the camplate on the same scale asFigs. 4. and 5. Figs. 7 to 13, inclusive, are part sections of thecamplate on the lines 00, w, x x, a), :0 and 9:. Figs. 14, 15,and 16 arerespectively front, side, and rear views of the folding sections drawnto double the scale of Figs. 4 to 13, and being one-third full size.Fig. 17 is a sectional view on line 03 Fig. 18 is a sectional view online 00 showing the side-folders turned part way up. Fig. 19 is asection on the same line as Fig. 18, but showing the side-folders closedquite up against the stock. Fig. 20 is a perspective view of theside-folder; Fig. 21, a similar view of the remover. Figs. 22 and 23 areside and front views of the shears. Figs. 24 and 25 are front andsectional views of the type-roll. Figs. 26 and 27 are similar views ofthe gluing-roll, the inner face of the wheel being removed; and Fig. 28represents the paper blank.

The whole of the working parts of the machine are carried by the strongiron frame A, which is supported by the legs a.

Motion is communicated from one part of the machine to another by trainsof gearwheels mounted on shafts journaled trans versely on the frame Aas follows, namely: The pulley B, which receives the driving-powerthrough the belt I), is secured on the shaft 0, which rests in the boxes0. On this shaft alsois keyed the gear pinion D, which drives thegear-wheel d on the shaft E. The wheel d drives the gear-wheel c,whichis centered on a pivot fixed in the standard 6, and by this motion iscommunicated to the connected train of gear-wheels F, G, and H, whichare centered on the shafts f, g, and h, respectivelyjournaled in theirboxes on the frame A, as shown. The wheel H meshes into a spur gearwheelon the cou nter-shaft I, which is journaled in the opposite sides of theframe A, and on which is 9 also secured the spur gear-wheel 6. By thisgear-wheel i motion is given to a train composed of gear-wheels J, K, L,and M, fixed, respectively, on the shafts j, k, l, and m. These shaftsrunin boxes held between the arms N N, I00

into the )ortions a (R and c U a a and which are adjusted by the rightand left hand screw-studs a. On the front ends of these shafts jt Z mare fixed the inking-rolls O, I, Q, and R, all in rolling contact onewith another and supplied with ink or any approved coloring materialfrom the vat S. The ink is thus conveyed down to the type-roll T on thefront end of the counter-shaft I, and which is in contact with theinking-roll O, and is provided with type or relief plates bearing thedevice or inscription which is to be printed on the boxes. The paper 0is coiled up in the reel p,(not shown in the plan view,) which issupported by the post g, standing on the frame A. The paper indescending from the reel passes first over the checlcrolls i" and s, bywhich it is prevented from running too freely into the machine. Fromthese it passes over the type-roll T,which prints the desiredinscription upon it, and against which it is held by the binding'roll Uon the shaft It. This type-roll is also provided with the adjustablespurs t, by which the slits a, Fig. 28, are made, thus dividing thecdgeof the paper The paper then passes through the guide 2;,over theglueroll V on the end of the coui1tershaft\V, and under the binding-rollw on the shaftf. In the glue-roll V a number of passages are made,radial in direction but of equal area through out. In these passages thestamps a are fitted so as to slide easily. The outer ends of thesestamps are made corresponding in size and shape with the glue-spots thatare suitable to u the size and shape of the box that is being made.

The circun'iferential face of the glue-roll is placed at some distancefrom the binding-roll above it and does not touch the paper that ispassing over it; but it is necessary that the stamps a protrude farenough to touch the under side of the paper, so as to deposit upon itthe glue which is on their ends. Theinner ends of these stamps areprovided with the laterally-projecting arms I)", which project into thecam-groove c", which is made in the disk X. This dish is placedcentrally in the glueroll, but is in no way connected with it, beingheld firmly stationary by the arm at", which is secured to the frame ofthe machine. The shape of this groove is such that as the gluerollrevolves, carrying the stamps a around with it, the stamps are heldwithin or with their outer ends flush with theface of the roll duringthe greater portion of their circuit; but as they approach the pointnearest to the binding-roll they are caused by the shape of the grooveto dart suddenly outward,spot the paper with the glue on their ends,andthen slide back into the glue-head. Before being moved outward, as abovedescribed, they pass under a scraper, e, which removes all superfluousglue from the roll. This glue-roll dips into the glue-vatY,\\'1iiel1contains the glue for the boxes. This vat is surrounded by an outercasing, between which and the vat itself steam or hot water isintroduced for the purpose of keeping the glue in a liquid state. Fromthe gluing-roll the paper passes directly onto the box-formingmechanism, which we will now proceed to describe.

On the front end of the shaft E is formed or secured the hubf the outerface of which is faced off accurately at right angles to the axis of theshaft. To this hub a number of the sections shown in Figs. 14, t5, and16 and on a much smaller scale in the general front view, Fig. 2, arerigidly attached, and swing around with the revolution of the shaft E,immediately in front of a stationary cam-plate, A, which is firmlysecured to a standard, A which is firmly bolted to the frame A, and bytheir contact with which the several parts of the sections are operated.These sections are precisely similar to each otherin construction andare operated in the same manner. B is the body of the section to whichall its worle ing parts are attached. A raised guide, I)", is fixedlongitudinally on the face of the body and has its outer end turned at aright angle, forming the stock 0, around which the paper is folded toform the box. The part marked 1') is the swinging block of the section.It swings in a gap formed in the body B, and is pivoted in it by the pin6. On the outerend of this block is pivoted a conical roll,f,whieh, byrunning upon a sloping margin, 9", of the cam-plate, controls the swingof the block 1).

Thejaw f is a rectangular body formed on or rigidly fixed to the blockI)", standing out forward at a right angle from it, and is so placedthat when the swinging block is thrown forward this jaw will be closedto the under side of the stock 0". Two sidefolders, g", are placed onopposite sides of the jaw, but are attached only to the block D by theirjournals or cylindrical portions h passing through closely-fittingbearings formed in it. The up per corner of each of these folders whichis adjacent to the upper side edge of the jaw is in line with the axisof the cylinder, so that the rotation ofthe folder in its hearings inthe block D" does not alter the relative position of these corners.

The first engagement of the section with the paper strip occurs when,having arrived at the lowest point in its circuit, its stock a has comein contact with the paper, as shown in Fig. 2, and the jaw f closes upagainst its under side, holding the paper fast against the stock 0". Thepaper is then cut off by the shears E, (shown in Figs. 22 and 23,) whichstand behind the sections. (SeeFig.2.) Theseshearsareseeured in place byscrews passing through their base i and into the holesj in thesection-bodies. The fixed blade is of the shears stands out horizontally from the section-body, and swings down upon the top side of thepaper strip. The working-blade Z is held open downward by the spring mon its pivot until the roller 02? on its outer end comes against the Vshaped cam F, passing under which closes the shears and sevcrs the paperstrip. This cam is held by the arm 0, which is secured to the frame ofIIC ceases 2 the machine. Should the spring from any cause fail to openthe shears immediately it has passed the angle of the cam, the roller awould come against the finger p by which the shears would be openedindependently ofthe spring.

Thejournalsof the side-folders project some distance from the rear sideof the section-body B, and have fixed on them the disks q",which havethe projections 7 and knobs s. Immediatel y the shears have severed thepaper, as above stated, the onward swing of the section brings theprojections r in succession against the rings or segmental guides i sothat by this means the disks are rotated and the sidefolders turned up,as shown in Fig. 19, folding the paper up against the sides of the stock0, the lips a on the sidefolders bending the ends of the paper-boxstrips so as to cross-lap above the stock, while the end lips, 0*, inthe same manner bend the portions of the paper marked a, Fig. 24, acrossthe end of the stock. The stamper G is then caused to descend upon theend portions of the paper above mentioned and the end-folder to close upthe end of the box by the mechanism hereinafter described The stamper Grslides on the raised guide D to which it is held by its wings h claspingthe guide-strips i" on the raised guide, its horizontal arm j closingdown the end portions of the box-strip against the stock 0. It receivesits reciprocating motion through the connecting-rod It, by which it isconnected with the crank Z on the shaft in. This shaft extends throughthe body B, and protrudes from its rear side, where it has fixed on itthe hub M. This hub has formed on it the two projections o andpfltheformer of which, by coming against the end of the ring H at q and thelatter at 9'", cause the crank l to turn downward and lower the stamper,so as to close and hold the glued ends of the boxstrips together.

The lip on the outer end of the horizontal arm bends the portions of thebox-strips down over the end of the stock 0 The endfolder 0, which iscentrally hinged to the jaw f next folds up the portion of the boxstripmarked (6 against the glued portions a. Soon after the stamper hasclosed down upon the box-strips the side-folders are turned backward bytheir springs (1, their disks having passed the ends of the segmentalguides t. Should the springs d fail to act, the side-folders would beturned back by the knobs s on the disks 9 coming against thereversingblocks y". The end-folder is operated by the bar 6", whichslides through theswinging block, and is connected with the lower end ofthe end-folder by the connecting-rodf". A spring, 9, holds the endfolder open, as in Fig. 15, except when the rear end of the bar 6, afterpassing through the channel h of the camplate, is moved against and upthe inclined plane 2', by which it and the lower ends of the end-folderare pushed outward. (See dotted lines, Fig. 15.) The raised course 9' ofthe cam-plate holds the bar outward until it reaches the receding slope7c, against which it is held by the spring g, and by which means theend-folder is again opened. Should this spring fail to operate at thispoint, the bar would be drawn back by its transverse groove Z engagingon the sloping finger m". The con tinued circulation of the section nextbrings it opposite a gap, N, in the rim of the cam-plate. The conicalrollerf of the swinging block drops into this gap, thus opening down thejaw f" from the stock. On the cam-plate and below the gap N is aspring-plate, N operating as a cushion to receive the rollf and preventshock to the swinging block as it falls into the gap. The jaw is heldopen during the remainder of its circuit by the segmental limb 0, insideof which the conical roller of the swinging block passes. The box isthen shoved off the stock by the hand 1). (Shown in Fig. 21.) Thefingers of this hand reach to the under side of the stock and a shortdistance under it from each side. The shaft to which the hand is securedslides through the body B, and is pivoted to an arm of the bellcrank Q,which is fulcrumed in the standard 1* on the section-body.

After the jaw has dropped away from the stock the inward-projecting arm5 of the bell-crank meets the cam T, which tilts the bell-crank, pushesthe hand 1') outward, and thereby shoves the box off the stock finished.A spring, a, is secured to the standard r and to the bell crank, bymeans of which the hand is held back against the raised guide, exceptwhen moved forward, as above described. Should the spring fail tooperate the bell-crank, it would be immediately reversed by itsinwardly-projecting arm coming against the inturning-guide '0. Vthen theconical roll of the swinging block has arrived at the lower end of thesegmental limb O, and just when the stock 0 has touched the paper strip,it comes against the slope w", by which it is thrown forward on thesloping margin 9 and the jaw f thrown up against the stock c.
